How To Assemble Tokens After Split

Hi,

How can I assemble all tokens after splitting original message read from
file ? I tried to assemble all token using aggregator but it did not work.

Can any one please tell me how to configure in XML DSL for this purpose ?
I'm using Apache Camel version 2.10

Following is my XML DSL :

<route id="route1">
<from uri="file:E:\\bankappfiles\\received?delete=true" />
<log message="The Full String :: [${body}]" />

<split stopOnException="true">
<tokenize token="~" />

<choice>
<when>
<simple> ${in.body} == 'oprncode=ATM'</simple>
<log message="=========>> ATM [${in.body}]" />
<aggregate strategyRef="aggregatorStrategy"
completionSize="3">
<correlationExpression>
<simple>${in.body}</simple>
</correlationExpression>
<to uri="file:E:\\bankappfiles\\atm\\" />
</aggregate>

</when>

<when>
<simple>${in.body} == 'oprncode=NEFT'</simple>
<log message="=========>> NEFT [${in.body}]" />
<aggregate strategyRef="aggregatorStrategy"
completionSize="3">
<correlationExpression>
<simple>${in.body}</simple>
</correlationExpression>
<to uri="file:E:\\bankappfiles\\neft\\" />
</aggregate>
</when>

</choice>

</split>
</route>

Thanks in advance
